Simple and capable, Any Base Converter is an unobtrusive 64 bit base converter that gets out of the way. Simply start typing in one of the predefined base fields and, as you type, the other base fields show the result. Conveniently placed separators and a mono spaced display font minimize errors. Double clicking any of the base fields will select a result section and triple clicking selects the entire result for a quick copy and paste into your applications with the option of keeping or removing the formatting.

Need to convert to an arbitrary base or convert to a negative value? Any Base Converter will handle this. For Arbitrary bases from 2 to 36, enter a base value and then enter another value to convert to or from the custom base. All values entered are also displayed as a signed base 10 number, based on the two's complement, that is sensitive to the bit depth of the entered value. For instance if the value is 8 bits or less, the negative value shown as an 8 bit two's compliment. The same is true for 16, 32, and 64 bit values.

Need to do a quick ASCII lookup? Type the character in and the other base fields will show the ASCII value. Entering any value will display an ASCII character if there is one.

Great Base Calculator

I am a programmer and I need to convert between bases all of the time. This is a fast little program that does just that without all ot the extra calculation.
Great App - Worth the $.99!

Not working as I wished!

This app does not understandt fractions.
Converting decimal #’s only is not the point for me.
converting fractions takes time. and this app does not provied that feature!!
I would love it if I am wrong and there is really a way in this app to convert fractions. otherwise it might just be a waste of money for me!
